An isolated point s statistic excluding method is proposed in this paper to eliminate crassitude error in clouding data, which include plenty of oddity data. The method based on the distance between two neighbour points can eliminate the data beyond normal distribution. A error limitation of angle and chordal highness method is used to filtrate clouding point.
